A. D. HOFFMAN, OF BELLEVILLE, MICHIGAN.

CIDEB-MILL.

Specification of Letters Patent No. 26,037, dated November 8', 1859.

To all whom 'it may concern:

Be it known that I, A. D. HOFFMAN, of Belleville, in the county of Wayneand State of Michigan, have invented a new and Improved Gider Mill andPress; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which*- Figure l, is aside sectional view of my invention taken in the line m, Fig. 2. Fig. 2,is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the twogures.

The object of this invention is to obtain within limited dimensions amachine that will crush apples and express the juice therefrom with buta small expenditure of power, the crushing and expressing operationbeing performed simultaneously and the juice separated from the pomace.

The invention consists in the employment or use of two crushing rollersone being toothed and the other correspondingly recessed to receive theteeth of the former one, and using, in connection with the crushingrollers, two pressure rollers and an endless apron, one pressure rollerbeing provided with yielding longitudinal bars and the whole arrangedand combined to operate insuch a manner as to elifect the desired resit.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents a rectangular frame which may be constructed in any properway to support the working parts. On the upper part of this frame therollers B, B, are placed transversely and side by side. The roller B,isprovided with teeth a, which are placed on the roller in spiral rows, asshown plainly in Fig. 2. 'Ihe roller B', has recesses 5, made in itsperiphery the recesses being also formed in spiral rows correspondinginversely with the position of the teeth a, and of such dimension as toreceive the same as the rollers rotate. A hopper C, is placed on theframe A, directly over the rollers B, B.

On the shaft of the roller B, at the outer side of the frame A, there isa toothed wheel D, into which a pinion b', gears. This pinion b', gearsinto a wheel c, which is on the shaft of a roller E, placed traverselyin the frame A, and parallel with the roller B.

The roller E, has a series of longitudinal and radial grooves d, made init and in each groove, a bar e, is placed, said bars having springs f,bearing against their inner sides and having a tendency to keep the barsthrust outward from the periphery of the roller. The roller E, iscovered by a piece of cloth or canvas g, which is allowed to lit looselyon the roller E.

Directly below the roller E, and in the same plane there is a roller F.The two rollers E, F, are about equal in diameter and they are made torotate simultaneously in consequence of a wheel h, gearing into thewheel c. The roller `F, has a smooth periphery.

Gr, is an endless apron which passes between the rollers E, F, andaround rollers z', i, in the frame A, said apron also passing underneatha trough H, in the lower part of the frame.

The pinion b, is placed on one end of a shaft I, the opposite end havinga toothed wheel J, on it, which gears into a pinion y', on the drivingshaft K.

The operation of lows: The apples are placed in the hopper C, and theshaft K, rotated by hand or any convenient power. The apples are crushedin passing between the rollers B, B, the teeth a, and recesses b,facilitating the crushing operation by insuring a uniformity of actionin consequence of their spiral position, and preventing all clogging ofthe apples in the hopper as the teeth serve as agitators. 'Ihe crushedapples fall on the apron Gr, which conveys them between the rollers E,F, the latter expressing the juice from them which falls into the troughH. The expressing of the juice from the crushed apples is greatlyfacilitated by the spring or elastic bars e, and cloth or canvas g,which give an intermittent pinching or pressing action, which adds tothe efficiency of the rollers. The juice falls at the inner sides of therollers, the pomace only passing between them, the pomace beingdischarged at the depressed or lowest part of the belt.

I am aware that crushing and pressure rollers and also endless apronshave been used for crushing apples, and expressing the the machine is asfoll juice therefrom, and I do not claim such derecesses b, and thepressure roller E, provice irrespective of the peculiarities convldedWith the yieldingbars e, and canvas neeted With the rollers as hereindescribed. covering g, substantially as nd for the` I claim therefore asnew and desire to sepurpose set forth. Y p 5 cure by Letters Patent, A.D HOFFMAN. p

The combination of the crushing rollers B, B', pressure rollers E, F,and endless Witnesses: aprons Gr, when the crushing rollers B, B', WM.O. VINING, Y are provided respectively with teeth a, and A. D. WRIGHT.
